Stock head casting flow numbers
Who did your heads and how does it run?
I would just like to hear some opinions with what you have and how it runs......Without turning into a big debate
considering a stock type bottom end, 374 casting ported and a custom grind......The car can be as nasty as anything but I want to get tags on it so I can run street classes.
Currently 3200#
Car is built to race and may need a new converter....has a 9" 4500 in it now

AI 190cc heads
.100 70/60
.200 146/115
.300 202/153
.400 244/172
.500 268/187
.600 275/193
4.030 bore not a 4.060 as some vendors listed and 2.00/1.56 Ferrea valves
Times are in sig. This is first and foremost a street car though 3400/3.73s 27" tires. I learned a little over the winter and hope it goes a little faster with that knowledge applied, will see when I get it to the track.

Lloyds heads from 3 years ago, before stages and the improvements he has made since.
.100 65.2 54.1
.200 137.2 109.4
.300 199.0 153.5
.400 241.1 174.1
.500 265.3 185.7
.600 268.8 192.5
The car so far has gone 12.64 in 95 degree heat with no track prep and some severe valve float. Full weight. This is also with a very small Joe O. cam. With the beehives I have picked up 500 more rpm and will have a better suspension set-up, including a set of MTs on some Bogarts. Looking for very high 11's, and then will spray it with a 100 shot. Stock 29k shortblock.
